This talk was amazing, get this speaker back, he mixes theory and tips with the right balance the most important thing is he shows the software as he speaks most just speak on and on loosing the audience.
According to Rick Hartley, just have one shared ground plane and ensure the signal and rf traces are spaced apart on the board by at least 20 times the dielectric thickness between signal and ground layer.
Great question and GrayOlson did repeat what Rick 'El-famous' said :D (I'm a Rick fan). I also have a pcb microprocessor combo (Esp32-c3-mini-u1). I need to look into Net-Ties and what they are. Also Mr Wilson recommended using C0G capacitors. I'll be rewatching this again, like I did with Rick's videos. Maybe find more. The important thing that Rick was saying is that you Don't split ground planes, as this will cause the plane to become an antenna (as seen by the trace of the split example) - this is where they mentioned Net-Ties as a possible solution. I'm sure after 3 years you may have found a better solution. Take care
